Jon Bon Jovi, Jewel and Mary J. Blige will help New York mayoral candidate Mark Green raise money at a benefit concert and dinner a week before the primary election.

Actors Warren Beatty and Annette Bening will host the event, which will be held September 5 at Town Hall, according to Green press secretary Joe DePlasco. Invitations to the shindig went out last week, DePlasco said. Dinner and the concert cost $1,000, while $50 buys balcony seats for the show only.

With Green leading a field of four Democratic candidates in polls, DePlasco said that since the fund-raiser is so close to the September 11 primary, funds would be used to campaign for the general election November 6.

Green scored the high-powered musical lineup with the help of some show-biz supporters, including MTV Networks chairman/CEO Tom Freston and VH1 president John Sykes, DePlasco said.

Green has served as New York's (first) public advocate since 1993. He worked with Ralph Nader on public-interest issues during the late 1970s and early '80s.
